✨ hdmi_vendor_infoframe_check(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for hdmi_vendor_infoframe_check(9) — yes that's the whole name, she's long, she's iconic, she's giving "I have a very specific job and I do it well" 💅

🌸 NAME 🌸

hdmi_vendor_infoframe_check — literally just: check a HDMI vendor infoframe. that's the vibe. that's the whole arc. 🎀

🦋 SYNOPSIS 🦋

int hdmi_vendor_infoframe_check (struct hdmi_vendor_infoframe *frame );

like, you hand her a pointer to a struct hdmi_vendor_infoframe and she gives you back an int. simple. clean. no cap. ✨

💖 ARGUMENTS 💖

  • frame — the HDMI infoframe. that's it. that's the argument. she's the main character of this function and she's getting checked 👑

🔥 DESCRIPTION 🔥

so what does she do? she validates that the infoframe is consistent 💫 and then she updates the derived fields — like, for example, length — based on the other fields. yes bestie, she's doing math-adjacent bookkeeping and she's slaying it 🧚

and the return value? get this:

  • 0 on success — we love a clean run, no notes 🫶
  • a negative error code on failure — 😭 she's telling you something went wrong and you gotta deal with it
fr fr, if you get a negative number back, that's not a vibe, that's an error. handle it. 💀
